This invention relates to machines for operating on work pieces, andmore particularly to machines for leveling the bottoms of shoes. Whilethe invention is herein illustrated with reference to that type ofmachine having a shoe support arranged for movements in directionslengthwise of a shoe thereon to carry the shoe below a level ing rollwhich thus acts progressively along the shoe bottom, and in Iwhich theleveling roll is arranged for tipping movements about an axis extendinglengthwise of the shoe on the support to impart the desired bottomcharacter to the shoe, it will be understood that the invention is notlimited in use, to machines of the type herein illustrated nor tomachines for leveling the bottoms of shoes.

An object of the invention is to provide means for controlling themovements of a work support relatively to a tool and the movements ofthe tool relatively to the support by the use of a singlemanually-operated member.

As a further object the invention has in view, in a machine in which thework support and the tool are each moved by power-operated means, theprovision of a control member operating in response to its movementalong one path to conitrol the power-operated means for moving the worksupport and in response to its movement along a path angularly relatedto the first path to control the power-operated means for moving thetool relatively to the work support.

More specically, it is an object of the invention to provide an improvedleveling machine in which the movements or" a work support in directionslengthwise of a shoe thereon to carry the shoe past a leveling roll, andthe tipping movements of the leveling roll relatively to the worksupport are both controlled by means of a single manuallynoperatedmember.

For the purposes in view and in acordance with a feature of theinvention, the work support is moved by a fluid pressure-operated memberand the tool or leveling roll is moved relatively to the work support bya second uuid pressure-operated' member, the fluid pressure-operatedmembers being controlled by valves which are in turn controlled by asingle manually-operated member. The speed, direction, and extent ofmovements of the work support and of the tool are controlled inaccordance with the speed, direction, and extent of movements of theControl member.

In accordance with a still further feature of the invention, themanually-operated member by which the movements of the work support andof the tool or leveling roll are controlled is capable of movingforwardly or rearwardly at any point in its movement laterally of themachine and is capable of moving laterally at any point in its movementforwardly or rearwardly of the machine.

The above and other features of the invention, including various noveldetails of construction and combinations of parts will now be moreparticularly described by referencey to the accompanying drawings andpointed out in the claims.

The invention is illustrated herein as embodied in a machine of the typeshown in Letters Patent of the United States No. 2,230,244 granted Feb-`ruary 4, 1941 on an application led in the names of Fred V. Hart andJohn J. Austin, The machine includes a main frame l0 within which ispivotally mounted a shoe support or jack I2 on a shaft i4. The jackincludes a toe post I6 fast on the shaft I4 and a heel post I8 looselymounted on the shaft I4. The toe and heel posts are locked together bymechanism controlled by an arm 20 after the shoe has been placed on thejack and after the heel post has been adjusted in position relatively tothe toe post in accordance with the size of the shoe to be operatedupon, as

described more fully in the patent referred to above.

The jack is moved by mechanism to be described about the axis of theshaft I 4 to carry the shoe rearwardly and forwardly beneath a levelingroll 22 which is arranged to be held against the bottom of the shoeunder heavy pressure as will be explained. This roll is mounted forturning movement on a rod 24 in a holder 26 pivotally connected at 28 toa carrier 30. This carrier is mounted for tipping movements laterally ofthe machine about the axis of a forwardly and rear- 3 wardly extendingshaft 32 supported in bearings at the top of the frame I0. The holder 26has a rearwardly extending arm 34 connected by a short link 36 to therearwardly extending arm 38 of a bell crank lever d fulcrumed at 42 tothe carrier 30. The bell crank lever 40 has a pair of downwardlyextending arms 4d carrying trunnions 46 extending into a circumferentialgroove 41 formed in a bushing 48 that is slidably mounted on the shaft32. Pivotally mounted on a laterally extending shaft '50 supported bysuitable bearings in the frame l0 is an upwardly extending arm 52 theupper portion of which is forked to straddle the bushing 48, the arms ofthe forked portion carrying trunnions 54 extending into acircumferential groove 55 formed in the bushing 48. Mounted on the shaft50 is a downwardly extending yoke member 58 and connected to this memberby a threaded rod 60 is a yoke-shaped member 62 between the arms ofwhich at their .s

upper end of the spring 12 bears against an abuty ment 'I4 pivotallyconnected at l5 to the frame l0. The upper end of the spring 'i0 engagesan abutment 'I8 pivotally connected to an arm 85 integral with the arm52. The springs l0, l2 act to move the arm 80 and with it the arm 52 ina clockwise direction duringr the leveling operation thereby to move thebushing 48 rearwardly along the shaft 32 thus rocking the bell cranklever 40 in a counterclockwise direction and forcing the leveling roll22 downwardly against the shoe bottom.

At the beginning of the leveling operation the roll 22 is lifted againstthe action of the springs '|0, 'l2 to prevent stubbing the toe end ofthe shoe during its movement beneath the leveling roll. For this purposethere is formed integral with the arm 52 a third arm 82 connected by anadjustable link 84 to one end of a lever 36 pivoted intermediate itsends to a bracket 66 secured to the frame I0. The lever 86 has itsopposite end portion forked to straddle a plunger 90, the arms of theforked portion carrying trunnions which extend into a peripheral grooveformed in the upper end of the plunger. This plunger is connected to apiston movable in a cylinder 92 so that upon admission of fluid underpressure into L the lower end of the cylinder the lever 86 is rocked ina counterclockwise direction thereby moving the arm 52 in acounterclockwise direction and moving the bushing 48 forwardly along theshaft 32 to lift the leveling roll against the action of the springs 10,l2.

Fluid under pressure is supplied by a pump 9d mounted in a reservoir S6in the bottom of the frame |0. Fluid from the pump is delivered througha pressure-regulating valve 98 which may be constructed as shown in theHart et al. patent, referred to above, and this valve is arranged sothat when the jack is in its forward position, as shown in Fig. 1, fluidis delivered directly from the valve back to the reservoir. However, thevalve is operated upon straightening a toggle mechanism |00 to deliveruid under high pressure to mechanism by which the roll 22 is tipped andby which the jack I6 is moved forwardly and rearwardly in the levelingoperation. This toggle is arranged to be straightened by a rod |02 whichis moved forwardly of the machine by a spring |04 upon the initialrearward movement of the jack, as fully described in the Hart et al.patent, Fluid under `pressure now flows 4` into the lower portion of thecylinder 92 lifting' the levelin T roll and upon further rearwardmovement of the jack, ilow of pressure iluid to the cylinder is cut offsubstantially at the time that the toe end of the shoe moves beneath theleveling roll, as shown in the Hart et al. patent, whereupon the roll isforced downwardly into engagement with the shoe bottom by the springs10, 12.

For tipping the leveling roll 22 during the leveling operation, thecarrier 30 has extending laterally from it an arm |06 to which ispivoted an adjustable link |66 the lower end of which is pivoted to alever l l0 keyed to a shaft ||2. This shaft is operatively connected forrocking movements to a uid pressure motor H4, as shown in detail in theHart et al. patent. Pressure fluid is conducted into the upper and lowerends of the riotor through pipes 6 and l 8 respectively, the directionof tipping movement of the leveling roll depending upon whether thepressure fluid is admitted into the upper or lower end of the motor. Forcontrolling the admission of pressure iluid into the motor |54 a valve|20 is provided, this valve being connected by a pipe |22 to thepressure-regulating valve 93. The pipes ||6 and ||8 are connected to theupper and lower ends of the valve 26 respectively whereas the pipe |22is connected to a mid portion of the valve. This valve includes a valveelement, as Shown in the Hart et al` patent, provided with an upwardlyextending rod |213 arranged when the rod is moved upwardly to permitfluid to flow from the pipe |22 through the pipe ||6 and when the rod|24 is moved downwardly to permit the fluid to flow through the pipe M8.With the rod in the midposition shown, the valve prevents ow of uidthrough either of pipes IIS, H8.

For operating the Valve |20 a bell crank lever |26 is fulcrumed at |28in the machine frame, one arm of this lever being connected by a pair oflinks |30 to a lever |32 one end of which is pivotally connected at |34to the rod |24, the other end of the lever |32 being connected to theupper end of a link |36 the lower end of which is pivoted at |38 to thelever ||0. When the bell crank lever |26 is moved in a counterclockwisedirection, as viewed in Fig. 1, the lever |32 moves downwardly about itsconnection to the link |36 thereby to admit pressure uid into the lowerend of the motor |4. The shaft ||2 is now turned in a counterclockwisedirection to tip the leveling roll and. at the same time to move thelink |36 downwardly whereupon the lever |32 pivots about its connectionwith the link |30 to lift the rod |24 moving the valve element in thevalve |26 back to mid-position. Thus there is provided a followupmovement so that the speed and extent of movement of the leveling rolldepends upon the speed and extent of movement of the valve element bythe bell crank |26. It will also be understood that the direction oftipping movements 'depends upon the direction in which the bell crank|26 is moved. The mechanism for moving the yloell crank to control thetipping of the leveling roll will be described later.

For impar-ting swinging movements to the jack l2 an arm |46 surroundsthe shaft |4 and is secured to the toe post i6 of the jack. This arm isprovided with segmental teeth |42 on its rearward portion and isconnected by gearing (not shown) with the rack of a fluid pressure motor|44 which is similar in construction to the motor H4. To the upper andlower ends of the motor |44 are connected pipes |46, |48 respectively,leading to the opposite ends of a valve |50 (Fig.

2) to the mid portion of which is connected a pipe |52 leading from thepressure-regulating valve 9B. The valve |50 includes an upwardlyextending rod |54 arranged upon upward movement to direct fluid underpressure through the pipe |46 into the upper end of the fluid pressuremotor |44 and when the rod |54 is moved downwardly pressure fluid flowsthrough the pipe |48 into the lower end of the motor |44, thereby tocontrol the direction of swinging movement of the jack.

'Ihe rod |54 has a head |56 to which is pivoted at |58 one end of alever I6!! the other end of which is connected by downwardly extendinglinks |62 to a rack |64. To the lever |68 are pivoted downwardlyextending links it connected to an arm |68 of a bell crank lever l'lllpivoted at |12 to the frame of the machine. The bell crank lever |78includes a downwardly and forwardly extending arm |74 to the lower endof which is pivoted a link |26 connected to a lever |18 pivotallycarried by the frame. Upon movement of the lever |18 in a clockwisedirection, as viewed in Fig. 2, the bell crank lever il@ is moved in acounterclockwise direction moving the forward end of the lever |66downwardly about its pivotal connection with the link |62 thereby movingthe rod |54 of the valve |55) downwardly and admitting pressure fluid tothe lower end of the motor Ult (Fig. l) whereupon the jack is movedrearwardly to carry the shoe beneath Ithe leveling roll. As shown in theHart et al. patent, this movement of the jack causes the rack |64 to bemoved downwardly whereupon the lever |68 pivots in a clockwise directionabout its connection with the links i6@ to return the rod |54. of thevalve to its mid-position. Thus it will be understood that the speed,direction and extent of movement of the jack depend upon the speed,direction and extent of movement of the lever llt.

For controlling the valves |20, |56, a hand lever |82 (Figs. 2 and 3) isfulcrumed upon a pin |24 carried by the parallel walls of a U-shaped arm|86. This arm is in turn fulcrumed at its lower` end upon a shaft |88carried by a boss |96 extending forwardly from the frame lil. Forlimiting movement of the lever |82 within the arm |86, the lever nearits upper end carries a bolt |92 which moves in slots |94 formed in theparallel walls of the arm |86. The lower end of the lever |82 is forkedat |95 to embrace the head |98 of a vertically extending pin 2t@journaled in an arm 22 which is in turn secured to the lower end of avertical shaft 264 journaled in the frame The head |68 of the pin 26|]is provided with spherical surfaces engageable with the inner surfacesof the forked end of the lever |82 to permit freedom of movement betweenthe lever and the pin upon movement of the lever about its fulcrum |84or upon movement of the iet about the shaft |38.

To the upper end of the shaft 2il4 (Figs. 4 and 5) is secured an arm 266which is in turn connected to one end of an extensible link 263 whichpasses through a sleeve 2li] held by a bracket 2 2 secured to the frameof the machine. The other end of the link 288 is connected to the lowerend of a depending arm 2 i4 (Figs. 2 and 5) of the bell crank lever |26Thus it will be understood that upon movement of the lever |82 laterallyof the machine about the pvot |84 the bell crank lever |26 is movedabout the pivot |28 to operate the valve |26 thereby to control thetipping movements of the leveling roll. The direction, extent and speedof tipping movement by a stop screw 248.

of the roll is controlled in accordance with the direction, extent andspeed of movement of thej lever |82.

Provision is made for insuring that the leveling roll will be moved to asubstantiallly horizontal position when the lever |82 is released by theoperator so that the roll will be properly positioned in its angularrelation to the shoe bottom at the beginning of the leveling operation.For this purpose springs 2|6, 2i8 (Fig. 5) surround the link 2M withinthe sleeve 2|@ and at their adjacent ends engage shoulders formed withinthe central portion of the sleeve. lThe outer ends of the springs engagecollars 225i, 222 respectively, near the outer ends of the link 288.These collars carry pins 224 which extend through slots 226 in thesleeve 2m to prevent turning of the collars with respect to the link 268when the op.- erator releases the lever |82. At the end of the levelingoperation the springs 2|6, 2|8 will cause the link 268 to assume amid-position with respect to the sleeve 2|@ in which the lever |82 is ina mid-position with respect to its movement laterally of the machine.

The lower end of the arm |56 in which the lever |82 is pivoted includesa forwardly extending projection 226 (Fig. 2) connected to the upper endof a downwardly extending link 228, the lower end of which is pivoted toan arm 23|! pinned to one end of a shaft 232 extending laterally of themachine. This shaft is carried by bearings 23|", in the frame lll atopposite sides of the machine. Pinned to the other end of the shaft 232(Fig. 6) is a forwardly extending arm 236 connected to an upwardlyextending link 23B the upper end of which is connected to an arm 24Dextending forwardly from the lever llt. It will be understood that whenthe arm |556 is moved about the shaft |65. by movement of the lever |62forwardly or rearwardly of the machine the lever |7|8 is caused topartake of a similar movement `thereby controlling, through theconnections heretofore described, the valve |5|l by which the swingingmovements of the jack are controlled.

The direction, speed and extent of movement of the jack will depend uponthe direction, speed and extent of movement of the lever |82 with thearm |66 about the axis of the shaft |83.

Mechanism is provided for lifting the leveling roll at any time duringthe leveling operation against the action of the springs lli, l2. Forthis purpose a treadle 222 (Fig. l) is pivoted at 244 to the frame ofthe machine and is urged upwardly by a spring '246 to a positiondetermined Connected to the treadle 242 is an upwardly extendingextensible link 250 hava slotted upper end Extending through the slot isa pin 254 carried by an arm 256 secured to a shaft 258. This shaftcarries an arm 266 pivoted at its upper end to the forward end of therod |2. The forward movement of the rod H32 under the action of thespring |04 during the leveling operation is limited by engagement of thepin 254 with the link 256 at `the upper end of the slot 252. If thetreadle 24'2 is depressed during the leveling operation thev rod |62 ismoved rearwardly causing the admission of pressure uid into the cylinder92 thereby lifting the leveling roll, as described in the Hart et al.patent.

It is desirable to limit the forward movement of the jack by the lever|82 during the leveling operation so that the toe end of the shoe willnot be carried forwardly of the leveling roll. For this purpose a latch252 (Fig. 2) is pivoted at 2.64 to an arm 265 depending from the lever|18. This amarres latch carries a pin 268 which rides' in' the slot 210in the upper end of a link 212, the lower end of which is pivoted at 21dto a treadle Z. This treadle is pivoted at '218 to the frame of themachine and is urged upwardly by a spring 280. The rearward end of thelatch 262 is recessed to form a shoulder 282 which engages a pin 234 inthe frame of the machine during the leveling operation to limit theforward movement of the jack. When the lever |82 is moved rearwardly atthe beginning of the leveling operation the latch 262 is carriedforwardly and urged upwardly by the spring 280 connected to the treadle276. Upon subsequent forward movement of the lever |82 the shoulder 262contacts the pin 2S@ at the proper time to limit the forward movement ofthe lever |82. The extent of upward movement of the latch 262 is limitedby a stop 286 carried by the arm 266. It will be understood that as thejack is moved rearwardly by .movement of the lever I 82 the latch 262will be carried out of engagement with the pin 28@ but the stop 285 isso located as to hold the latch 262 in the proper position so that theshoulder 282 will move into engagement with the pin 286i to limit theforward movement of the jack. At the conclusion of the levelingoperation the treadle 276 is depressed to withdraw the latch 262 fromengagement with the pin 284 so that the jack may be moved back into itsloading position as shown in Fig, 1.

From the above it will be seen that I have provided a leveling machinein which a single hand lever 82 is employed to effect the tippingmovements of the leveling roll and the movements of the jack to carrythe shoe forwardly and rearwardly beneath the leveling roll in theleveling operation. The direction, speed and extent of movement of thejack and of the tipping movements of the leveling roll are controlled inaccordance with the direction, speed and extent of movements of thelever 82.
